I should point out that my interest (and focus of this blog post) has always been firmly in the “engine room” side of development - the sysadmin, DevOps, back-end infrastructure world.

Now, I’m conversant in front-end technologies, having been a “webmaster” since the late 90s when we were all slicing up images in Fireworks, wrestling with table-based layouts and running random stuff from Matt’s Script Archive for our interactive needs.
